I am not quite sure what you mean, but if you want the data sheet to your
serial port, you have to contact its producer.

If you want to know how to write a device driver you should post that
question to a linux developer newsgroup.

Hey, be more optimistic. Most of the behavior of serial ports
was settled 25 years ago. A few popular UART chips established
a de facto standard that has been followed ever since.

Go to Wikipedia and look up serial_port and UART. You will find
pointers to specific UART chips, whose spec sheets are no doubt
available online. The serial port in your PC is very likely to
act just like that.
